This invention pertains to the manifolding art,

wherein superposed continuous record strips are progressively advanced past a recording position, and more particularly to means and method for automatically interchanging fresh carbon or transfer material interleaved between the record strips for exhausted sheets thereof in timed sequence with advancement of the record material.

Carbon or transfer material, however good the quality, wears outafter a number of repetitious recordings long before an entire supply packet of record material is exhausted. One effort heretofore to obviate the difliculty was by use of continuous strips of one time" carbon interleaved between the record strips and advanced in unison therewith. Such method wherein each area of the transfer material afforded but a single writing and was then discarded was extremely wasteful and expensive, even though a comparatively poor quality of carbon material was employed. The carbonized surface of the interleaved transfer material, even of poor quality, is capable of at least limited repetitious use in production of plural record impressions from one transfer area.

In autographic registers and imprinting apparatus it has not been uncommon to advance interleaved carbon transversely of the record strip little by little, either manually or automatically by the differential advancement of the record strips.

- Otherwise the interleaved carbon material must be manually changed periodically to provide fresh transfer surfaces.

In the present instance a succession of individual sheets of transfer material are interleaved at longitudinally spaced intervals between the superposed record strips and as the record strips are progressivelyadvanced past the recording position -a set of superposed transfer sheets are temporarily arrested in the recording position until a predetermined number of sets of record forms have been advanced therebeyond, and the arrested strips have been repetitiously used until approximately exhausted whereupon the arrested set of transfer sheets is automatically released and discharged from the recording apparatus and is replaced by a fresh set of transfer sheets,

which in turn are arrested at the writing position.

The object of the invention is to improve the means and method of making manifold copies of records, and provide apparatus for automatically interchanging fresh transfer material for worn and exhausted material which is not only simple in construction and capable of being economically constructed, but which will be eflicient in use, automatic in operation, uniform in action, having minimum operatingparts and be unlikely to get out of repair.

A further object is to provide a method of antomatically interchanging fresh carbon or transfer sheets for used and exhausted sheets periodically without special attention of the operator.

A further object of the invention is to provide means for temporarily arresting carbon or transfer sheets interleaved between intermittently advanced continuous record strips at a recording position, and thereafter automatically releasing the arrested transfer material for replacement with fresh material.

A further object of the invention is to provide a recording apparatus equipped with automatic transfer material interchanging devices.

A further object of the invention is to provide a recording apparatus embodying an automatic transfer material interchange mechanism possessing the advantageous structural features and meritorious characteristics and mode of operation herein mentioned.

The assembly of record strips and interspersed transfer sheets for use with an automatic transfer interchange apparatus as herein described forms the subject matter of a separate application for patent Serial No. 444,857 filed concurrently herewith.

With the above primary and other incidental objects in view as' will more fully appear in the specification, the invention intended to be protected by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or illustrated in the accompanying drawings.

In the drawings, wherein is shown the preferred but obviously not necessarily the only form of em-, bodiment of the invention,

Fig. 1 is a. longitudinal sectional view of a conventional type of autographic register to which the present invention has been applied.

Fig. 2 is a top plan view thereof.

' Fig. 3 is a transverse sectional view of the autographic register showing the relation of the transfer material arresting means.

Fig. 4 is a plan view of a portion of a manifolding assembly of record strips and interleaved longitudinally spaced transfer sheets for use in a recording apparatus equipped with transfer sheet arresting and interchange devices.

Fig. 5 is a perspective view illustrating the relation of successive sets of transfer sheets at the moment; of interchange.

Like parts are indicated by similar characters of reference throughout the several views.

While for illustrative purposes the transfer material' interchangeldevices and mode of operation have been shown and described in relation with a conventional type of autographic register, it is to be understood that it is not limited thereto, but in suitable size and proportion may bereadily adapted to other writing and imprinting apparatus.

Referring to the drawings, l indicates an autographic register cabinet having therein a supply compartment 2 to receive a packet l of continuous series connected detachable form statione y. and a storage compartment 4 for at least a part of the inscribed portions of the record strips, the remainder of which are torn off as they are ejected from the register.

The superposed record strips 5, in the present instance are marginally punched at 6 for engagement of revoluble pin wheels I by which the strips it which are positioned to arrestadvancing transfer material sheets in the writing position, until the traction influence thereon becomes suflicient to overcome the tension of the detent finger springs II, which upon yielding release the arrested transfer material. The addition of the yielding fingers l and springs II is "the only change or addition to a conventional autographic register which is necessary to accommodate the present automatic transfer interchange opera.- tion.

The manifolding assembly which includes the interchangeable transfer material comprises a plurality of superposed record strips which are divisible at spaced intervals upon transverse weakened lines I2 into sets of individual sheets.

Distributed at spaced intervals throughout the length of the record strips are corresponding sets of transfer sheets 13 interleaved between the record strips. The relative spacing of the transfer material sets is somewhat dependent 'upon' the quality of the material, or the number of copies which may be made therefrom before the transfer surface is exhausted. Ordinarily commercial transfer material has a capacity of thirty to. fifty writings. mated capacity is fortytransfer records, the sets of transfer sheets I; will be interleaved between every fortieth set of separable record sheet comprising the superposed strips.

However, the distribution of the record material may be at greater or less intervals which are preferably but not necessarily of equal extent.

ing margin with an attached transverse anchor 'strip. ll of thin, relatively stifi material. This may be a paper hinder or a cardboard strip the Assuming that the esti-v Each transfer sheet I3 is provided at its trail-' The projecting ends of the anchor strips I are preferably notched or shouldered to facilitate location of the transfer sheets during manufacture of the manifolding assembly, and for locating engagement with the detent fingers ll of the recording apparatus.

The leading ends of the transfer sheets are securely attached to the accompanying strips 5 of record material. The record material sheets it are preferably stapled to the over and underlying record strips by wire staples l5 positioned quite closely to the leading margins ofthe transfer sheets. To enable the record strips to be relatively adjusted in unison with their advancement by the pin wheels 1. to insure proper registry of printed matter thereon, the staple l5 loosely holds the assembly together with freedom for limited movement vertically and longitudinally as is described in the copending application for Letters Patent Serial No. 395,629 of Urban M.

. Falter, filed May 28, 1941. However, other means of interconnection may be employed and such loose staple attachment is not essential to the present disclosure.-

The record strips are of greater tensile strength than the transfer sheets and as the strips are advanced by the pin wheels 1, or other strip feeding means, the transfer sheets are advanced in unison thereby, with minimum tension .or strain, until the projecting ends of the anchor strips i4 engage the detent fingers i0.

The interenga-gement of the projecting ends of the anchor strips M with the detent fingers Ill arrests the advancement of the particular set of transfer sheets i3. The tensile strength of the transfer material being'less than the tension to the arrested set of transfer sheets. The arrested set of transfer sheets are repeatedly used to make record impressions upon succeeding sets of record portions of the strips, until the transfer surfaces of the arrested sheets are exhausted.

With each advancement of the record strips to present successive sets of record receiving areas thereof in registry with the arrested transfer sheets, the next succeeding set of transfer sheets is also advanced through step by step movement toward the arrested set thereof.

As the set of transfer sheets thus advancing with the record strips approaches the recording position, the staple i5 thereof engages the anchor strips ll of the arrested set of transfer sheets then in record making position and which by such time have been substantially worn out or exhausted. The record strips being of greater tensile strength than the detent finger springs II, the thrust of the staple [5 of the advancing set of transfer sheets under influence of further advance of the record strips 5, against the anchor bars I of the arrested set of sheets overcomes the yielding resistance of the detent fin- .gers It. The detent fingers yield. against-the tension ,of their springs to permit the ends of the anchor bars ll of the exhausted set-of transfer sheets to pass therebeyond and so frees the set of worn out transfer sheets, which then continue out of the register in unison with further advancement of the record strips. The detent fingers are returned by their springs to ,upright position to engage the ends of the anchor bars ll of the advancing set of fresh transfer sheets.

However, as before stated the tensile strength of the transfer material being less than the resistance of the detentfinger springs, when the "advancement of the new set of transfer sheets is arrested by the detent fingers, the continued movement of the record strips causes the staple II to tear out of the leading margins of the transfer material leaving the substitute set of transfer sheets at rest in recording position, until releasedand displaced by a subsequent set thereof.

The sets of transfer material are detachably secured at spaced intervals to the record strips. Each set of transfer sheets is in turn caught by the detent fingers iii in recording position, and is automatically detached from the conveyor strips by tearing strain upon the transfer material. It is so helduntil the succeeding set of transfer sheets is advanced to the interchange position. There'upon then exhausted set of sheets is pushed ahead by the tractive power of the record strips which overcomes the yielding .resistance of the detent fingers until the exhausted set of sheets is released thereby. The oncoming set of fresh transfer sheets is then arrested in like manner by the detent finngers and so held temporarily in completion of the cycle.

Thus at each cycle of operation a set of fresh transfer sheets interleaved between the record strip is interchanged for an exhausted set of transfer sheets also interleaved between the record strips at the end of a predetermined sequence of writing operations upon the record strips which will have been advanced independently of the positioned transfer strips through a predetermined travel range.

The fact that the transfer sheets are interfolded with the record strips while in the pack, and the travel distance from the pack to the re cording position is relatively short, it is unlikely that the transfer sheets or their anchor strips will become laterally displaced or shifted into askew relation. However, as a precaution to guard against such displacement, upstanding guide flanges l6 are provided in parallel relation with the path of travel of the record strips. The guide flanges are so spaced as to permit free movement of the anchor strips l4 therebetween. The forward ends of the guide flanges l6 are slightly flared at IE to deflect the ends of the anchor strips l4 inwardly in event of lateral displacement. v

In the event that pin type feeding means is employed, the point of engagementis so located that at the end of the feeding movement by which exhausted transfer material is pushed from recording position, the feed pins will come to rest behind the anchor strip ll of the displaced transfer sheet. This entirely frees the displaced transfer material which may then be immediately removed. Otherwise, the ends of the anchor strip i4 might be held by the feeding pins until the succeeding operation. However, it is to be understood that pin type feeding devices are not essential, and the invention is not dependent thereon. Frictional or other feeding means may be substituted therefor.

From the above description it will be apparent that there is thus provided a device of the char.

(ill

acter described possessing the particular features of advantage before enumerated as desirable, but

which obviously is susceptible of modification in its form, proportions, detail construction and arrangement of parts without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has been described in language more or less specific as to structural features; it is to be understood that the invention is not limited to the specific features shown, but that the means and construction herein disclosed comprise the preferred form of several modes of putting the invention into effect, and the invention is therefore claimed in any of its forms or modifications within the legitimate and valid scope of the ap. pended claims.
